On Christian Doctrine

De doctrina Christiana (English: On Christian Doctrine or On Christian Teaching) is a theological text written by Saint Augustine of Hippo. It consists of four books that describe how to interpret and teach the Scriptures. The first three of these books were published in 397 and the fourth added in 426. By writing this text, Saint Augustine set three tasks for Christian teachers and preachers: to discover the truth in the contents of the Scriptures, to teach the truth from the Scriptures, and to defend scriptural truth when it was attacked. One of Saint Augustine's most important contributions to Christian Theology, "On Christian Doctrine" is essential reading for any serious believer interested in learning more about faith in God. The four books of St. Augustin On Christian Doctrine (De Doctrina Christiana, iv libri) are a compend of exegetical theology to guide the reader in the understanding and interpretation of the Sacred Scriptures, according to the analogy of faith. The first three books were written ad 397 the fourth was added 426. It is the first and best patristic work on biblical Hermeneutics, and continued for a thousand years, together with the Prefaces of Jerome, to be the chief exegetical guide. Although it is superseded as a scientific work by modern Hermeneutics and Critical Introductions to the Old and New Testaments, it is not surpassed for originality, depth and spiritual insight.
